Testing
SECTION 6
6.1 Testing the Cable
IMPORTANT: Do NOT supply the system with electric current to test.
All testing should be done with a digital ohmmeter or PowerMan™. Supplying the system with a 120V or 240V electric
current before the installation is complete is not needed to test the system.
6.2 Take the Ohm Readings
The electrical resistance of the WarmlyYours TempZone™ Floor Heating Cable (Twin) must be checked before you start and
monitored throughout the installation process to ensure there has been no damage causing shorts or breaks.
We recommend at least three readings be taken:
1. Before starting installation
2. After securing the cable in place on the subfloor
3. After installing the flooring surface on top of the cable
Use an ohmmeter or PowerMan™ to measure the resistance. Refer to section 5.3 for instructions about how to use the
PowerMan™.
6.3 Record the Ohm Readings
The value on the UL label should be within -5/+10% variance at 20ºC (68ºF) of the original measurement indicated on the
label. The electrician should carefully mark the initial ohm reading taken onto the warranty card in section 10. Should the
initial ohm reading be outside the -5/+10% variance, refer to section 8, Troubleshooting, or call WarmlyYours Technical
Support at (800) 875-5285.

Heating Cable (Twin) product label. Figure 8 depicts a sample product label. The information provided in the figure is for
